SAM3U Series
Supply Monitor
Figure 19-3. No Separated Backup Supply Powering Scheme
Note:
The Supply Controller embeds a supply monitor which is located in the VDDBU Backup Power
Supply and which monitors VDDUTMI power supply.
The supply monitor can be used to prevent the processor from falling into an unpredictable state
if the Main power supply drops below a certain level.
The threshold of the supply monitor is programmable. It can be selected from 1.9V to 3.4V by
steps of 100 mV. This threshold is programmed in the SMTH field of the Supply Controller Sup-
ply Monitor Mode Register (SUPC_SMMR).
The supply monitor can also be enabled during one slow clock period on every one of either 32,
256 or 2048 slow clock periods, according to the choice of the user. This can be configured by
programming the SMSMPL field in SUPC_SMMR.
Enabling the supply monitor for such reduced times allows to divide the typical supply monitor
power consumption respectively by factors of 32, 256 or 2048, if the user does not need a con-
tinuous monitoring of the VDDUTMI power supply.
Restrictions: With Main Supply < 3V, some peripherals such as USB and ADC might not be oper-
ational. Refer to the DC Characteristics of the product for actual possible ranges for such
peripherals.
